FILTER.

Speccaton of Letters Patent.

Patented Dec. 25, 1906.

Application filed March 26,1906. Serial No. 308,137.

To a/ZZ 1072/0711/ t may concern:

Beit known that 1, LLOYD VINCENT Roon, a citizen of the United States, residing at Marietta, in the county of W'ashington and State of Ohio, have invented a new and usei'ul Filter, of which the following is a speciiication.

This invention relates to filters of that general class shown in United States Letters 1j atent granted to me on the 6th day of February, 1906, under No. 811,644.

The object of the invention is to improve, simplify, and cheapen the construction of the filter and to provide a transparent casing or housing for the same whereby the condition of the filtering material may be observed from time to time without the necessity of detaching the several parts.

A further object of the invention is to provide improved means for cleaning the ltering material and means whereby the cleaning brushes or Scrapers may be adjusted laterally with respect to the filtering material to oompensate for wear upon the latter.

A still further object of the invention is to generally improve this class of devices so as to increase their utility, durability, and efficiency,as well as to reduce the cost of manufacture.

l/Vith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being understood that various changes in form, proportions, and minor details of construction may be resorted to within the scope of the ap pended claims.

In the accompanying drawings, forming a part of this specication, Figure 1 is a side elevation of a filter constructed in accordance with my invention. Fig. 2` is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view taken on the line 3 3 of Fig. 2. Fig. 4 is a bottom plan view of one of the slotted brackets. Fig. 5 is a side elevation of a portion of one of the filtercleaning devices.

Similar nmnerals of reference indicate cor responding parts in all of the figures of the drawings.

The improved filter comprises a pair of spaced heads 5 and 6, one of which is provided with perforated lugs in which are seated clamping-rods 7 the opposite ends of said rods being threaded through similar lugs formed of glass or similar transparent material, so that the contents of the lilter may be readily `inspected from time to time. The head 5 is retained in position on the flange 6 by means of a clamping member or yoke 10, the free ends of which engage suitable lugs or projections 11, secured to said flange, so that by adjusting the clamping-screws 12 the parts may be securely locked together. or head 5 is formed with an enlargement 12', having a loiigitudinally-disposed passage 13 formed therein, which communicates With a draw-oil valve or cock 14, through which the filtered water is discharged, there being a similar passage 15 formed in the enlargement 16 on the head 6 for withdrawing the water through a similar cock or faucet. Threaded in an opening 1S in the cap or head 5 is a pipe or tube 1S, the lower end of which is conical in shape and provided with a plurality of perlorations or openings 19, which communicate with the interior bore 2O of a filtering element 21, preferably in the form of a cylindrical block of porous material.

The tube 1S is provided with spaced later ally-extending flanges 22 and 23, the lower flange 23 of which engages the adjacent sur- 'face of the filtering element 21, said element The cap being retained in contact with the flange 23 l by means of a rod 24., threaded in the reduced end of a tube 18 and extended longitudinally of the bore 20. The free end of the rod 24 passes through a threaded opening in alcap or closure 25, fitting within the bore 2O at the lower end of the iiltering element, said rod being loosely mounted in a horizontally-disposed bar 26, extending transversely of the casing and spaced a short distance from the head 6, as shown.

Disposed above the filtering element 21 and mounted for rotation on the iiange 22 is a water-wheel 27, provided with a plurality of non-radial blades 2S andl to which the water is delivered through an inlet 29, formed in a lateral enlargement on the flange 8, as shown. The inner portion of the inlet 29 is reduced at 30, and the walls of the flange 8 adjacent the reduced portion 30 enlarged at 31, so as to give a clearance to the incoming stream of water and prevent spreading thereof, whereby the Water is compelled to strike the blades 2S in a compact stream,

which produces a more effective rotation of the wheel. At the opposite sides of the inlet 29 the flange 8 is provided with an internal enlargement or shoulder 32, fitting closely to the outer periphery of the edge ofthe Wheel and slightly underlapping the same, as indicated by dotted lines in Fig. 3 of the drawings, thereby to prevent the incoming water from escaping downwardly without actuating the wheel, said shoulder or enlargement extending a comparatively short distance around the interior walls of the fiange 8 in order that there be an annular space between the remaining portion of the wheel and said flange to permit the water to escape into the body of the filter.

Secured to the bottom of the water-wheel 27` are inwardly-extending brackets 33, each provided with a longitudinally-disposed slot 34, in which are mounted for lateral movement longitudinally-disposed rods or bars 35, the lower ends of said. bars being passed through slots 36, formed in the opposite ends of the bar 26. The ends of the bars are threaded for engagement with suitable clamping-nuts 37, whereby said bars may be securely locked in adjusted position. The intermediate portions of the bars 35 are offset to form centrally-disposed crank-arms 38, which serve to support the filter-cleaning devices. Slidably mounted on the crank-arms 38 are sliding collars 39 and 40, connected through the medium of links 41 to a weight 42, that is also connected by similar links 43 to the cleaning device, preferably in the form cfa bar or scraper 44. The sleeves or collars 39 are rigidly secured to the crankarms' by means of suitable screws or similar fasteningdevices 45, while the sleeves 40 are free to slide on said arms, so that as the rods 35 are rotated through the medium ofthe water-wheel the weights 42 will be thrown outwardly by centrifugal force, and thus hold the bars or Scrapers 44 in contact with the filtering element. While the cleaning devices are preferably in the form of bars or Scrapers, it is obvious that brushes or strips of emery, steel, or other suitable material may be employed, if desired.

By having the cleaning devices mounted on the rods in the manner described the bars 44 may be adjusted laterally with respect to the filterin element by sliding the rod 35 longitudina y of the slots 34 and 36 and clamping the same by adjusting the nuts 37, a further adjustment of the bars or cleaners 34 being effected by partially rotating the crank-arms 38, as will be readily understood.

In `operationwater is admitted through the inlet 29, whereupon the wheel 27 is rotated by the incoming water and the cleaning` devices or bars 44 rotated around the stationary filtering element 21. As the water escapes from the wheel and passes downlates through the filtering element to the bore or passage 20, through which it rises to the passage 12 in the cap 5 and may be drawn off at the cock or faucet 14. At the same -timethe dirty or impure water may be drawn 0H through the cock or faucet 17 without fouling the filtered water Within the longitudinal bore of the filtering element. During the rotation of the cleaning mechanism around the porous block or filtering element the bars or cleaners 44 will be maintained in frictional engagement with said filtering element under thel centrifugal action of the crank-arms and weights 42.

By having the casing or housing formed of glass or other transparent material the contents of thefilter may be observed from time to time without the necessity of detaching the several parts, while by reason of the shape of the inlet 29 the water is forced under pressure in contact with the blades of the water-wheel thereby eectually rotating the latter.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art, and further description thereof is deemed unnecessary.
